| 特殊工況下橋上縱連板式無砟軌道無縫道岔溫度力研究(50 卷) |
| 英文標題 |
| Study on temperature stress of welded turnout of continuous-slab-track on bridge in special operating conditions |
| 摘要 |
| 為進一步研究橋上縱連板式無砟軌道無縫道岔受力和變形的特點，分析了其在實際工程中常見的底座板發(fā)生收縮徐變、底座板存在施工溫差和底座板斷板三種工況下溫度力的變化規(guī)律。基于梁軌相互作用關系，建立了“岔—板—橋—墩”一體化空間計算模型,利用有限元法,編制了相應計算 |
